Let's solve this step by step. The image is a worksheet about the
male reproductive system, where you're asked to:
1.
Label the parts of the male reproductive system using numbers 1–7.
2.
Write the function of each part in the table below.

Step 1: Identify the labeled parts
Based on standard anatomy and the diagram provided (which is a typical illustration of the male reproductive system), here’s what each number likely refers to:
-
1:
Testis (plural: testes)
-
2:
Penis
-
3:
Epididymis
-
4:
Vas deferens (also called ductus deferens)
-
5:
Seminal vesicle
-
6:
Scrotum
-
7:
Ejaculatory duct
> Note: The numbering may vary slightly depending on the diagram, but this matches common labeling in such educational worksheets.

Step 2: Write the function of each part
Now let’s go through each one with its correct function:
| PART | FUNCTION |
|------|----------|
| 1 |
Testis – Produces sperm (spermatogenesis) and testosterone (the main male sex hormone). |
| 2 |
Penis – Delivers sperm into the female reproductive tract during intercourse; also used for urination. |
| 3 |
Epididymis – Stores and matures sperm after they are produced in the testes. |
| 4 |
Vas deferens – Transports mature sperm from the epididymis to the ejaculatory duct. |
| 5 |
Seminal vesicle – Produces a significant portion of the seminal fluid (semen), which nourishes and protects sperm. |
| 6 |
Scrotum – Holds the testes outside the body to maintain a lower temperature (about 2°C cooler than body temperature), which is necessary for sperm production. |
| 7 |
Ejaculatory duct – Formed by the union of the vas deferens and the duct from the seminal vesicle; carries sperm and seminal fluid to the urethra. |

Final Answer Table:
| PART | FUNCTION |
|------|----------|
| 1 | Produces sperm and testosterone |
| 2 | Delivers sperm and urine out of the body |
| 3 | Stores and matures sperm |
| 4 | Transports sperm from epididymis to ejaculatory duct |
| 5 | Produces fluid that makes up part of semen |
| 6 | Keeps testes at optimal temperature for sperm production |
| 7 | Carries sperm and seminal fluid to the urethra |

✔ This completes the worksheet. Each part is correctly identified and explained in terms of its biological role in the male reproductive system.
Parent Tip: Review the logic above to help your child master the concept of reproductive system worksheet.
